To all whom it may concern:

Be it known that I, HERMAN G. TonKE, a

citizen of the'United States, and resident of Plymouth, in the county of Sheboygan and State of Wisconsin, have invented certain new and useful Improvements in Road Scrapers or Drags; and I do hereby declare that the following is a full, clear,- and exact description thereof. 7

. My invention relates to certain new and useful improvements in road scrapers or drags and refers particularly to improvements in what is generally known 'to the trade as King drags, employing ascra-ping member comprising two forward inclined blades and a central rear blade for leveling the earth. I

The primary object'of the present inven tion is to provide novel and efficient means for lifting the scraping member from engagement with the surfaceof the road.

A further object of my invention is the provision of means for selectively tilting either side of the scraping member to give the crown of the road its proper angle.

And a still further object of this invention is to provide means for securing the scraping member in the desired adjusted position; and to further provide means for equally distributing thed'raft of' the scraper.

- With the above and other objects in view which will appear as the description proceeds, my inventionconsists in the novel construction, combination and arrangement of parts, substantially as hereinafter described and moreparticularly pointed out in the appended claims, it being understood that changes in the precise embodiment of'the invention herein disclosed can be made without departing from the tion. 7 1

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised'for the practical application of the principles of my invention.

Figure 1 is a view in plan looking at the spirit of the inven- Fig. 2 is a vlew in elevation looking at the rear end thereof.

Fig. 3 is a view in side elevation of my road scraper, the road scraping member being shown as lifted from. engagement with theroad surface.-

Fig. 1 is a view similar to Fig. 3, the road scraping member being shown as in operative position.

Fig. 5 is a .detail'view of the means for locizing the truck in its adjusted position, an

Fig. 6 is a detail view of the pawl and ratchet used to retain the scraper member in its adjusted position.

My invention is used in connection with what is termed as a King drag or scraper, comprising the ballast receiver 1, carrying the two oppositely inclined scraper bladess2, and the central evening blade 3, all of well known construction, and this scraping member is operated or drawn by means of the extensible truck 4, having the usual fore guiding wheels 5,.carrying the tongue 6 for attachment thereto of any suitable draft means which may be horses or any mechanical'tractor, and the rear wheels 7 mounted upon the extension 8 slidably mounted upon the side members 9 of the truck 4, as here inafter described.

This extension 8 consists of the two sid trusses 13 being provided for the extension,

running from the rear'axle to the forward end of the side members 10.

For operating the extension 8 to lengthen or shorten the wheel base of the truck, a rack 14 is secured to each of' the sides 9 of the truck near the rear end thereof, having in mesh therewith the gear pinions 15 carried by a shaft '16 journaled in bearings mounted upon the extension side members ratchet 21 for securing the same in adjusted position. Y

By reference to Figs. 3 and 4 of the drawings it will be readily seen that when the truck is extended the scraping member is lifted from engagement with the surface of the road and that when the truck is short ened the scrapmg member is allowed to engage the roads surface. Tl'llS is accom- 22 secured at one end to the inclined blades and at their tt'orward ends to the truck, the outer connections being secured at 23 to' the side members 9, and the inner connections being secured at 24 to the front bolster, and the chain or other connections 25 connected, one at each side of the blade 3 and at 26, to the extension 8.

Thus it will be seen that when the truck is'extended the draw connections 22, which may be'chains, or any desired connections, and the chains 25 are tightened, thus lifting the scraping member, as will be obvious; and to support this greatstrain the truck is braced by the trusses-27;

In order to tilt the scraping member to give the proper crowning to the road, the

ber from operative hand wheels 28 fixed to the shafts 29' carry ing on their outer ends the drums 30, are employed. These shafts 29' are journaled in bearings 31 secured to the trusses 27, and are supported or independently secured in place between the trusses by means of the sleeve 32. Fixed to the scraping member at 38 are the ropes or other connec tions 34 having their free ends engaging the drums 30, and to secure the scraping member in its adjusted position, the ratchets 35 are employed secured to each shaft'QS) intermediate the Wheels 28 and the trusses, and adapted to be engaged by the paavls 36 carried by said trusses, as shown in From the foregoing description taken in connection with the drawings the operation of invention will be readily apparent: and further description is thought unnecessary, and so to equalize the draft to. insure the proper scraping of the road a suitable draft equalizer 37 is employed, having the connections 38 leading to the scraping member; I

'What-is claimed is:

1. A road scraper comprising a'support ing frame including extensible sections, a

road scraping. member having connections with the sections, and means for extending the frame to lift the scrapingmember from operative position.

. 2. A road scraper comprising. a portable extensible truck, a road scraping member in -termediate the ends thereof, flexible connections betweenthe scraping member and the truck, said connections. leading from the rear. and front portions of the scraping gmember-tothe rear and front por-tlons re spectively of the truck. and means for extending: said ti 'uck-to lift the scraping memei'igagement with the surface-of the road.
